CREAMsGAGE FOR MILK-CANS.

SPECIFICATION forming part of Letters Patent N 0. 291,296, dated January1, 1884. Application filed April 7, iss. (No model.)

To all whom, it may concern;

Be it known that I, CLARENCE L. COLBY, a citizen of the United States ofAmerica, residing at Fairmont, in the county of Martin and State ofMinnesota, have invented certain new and useful Improvements inCream-Gages for Milk-Cans, cation.

This invention relates to cream-gages for milk-cans; and it consists inthe peculiar construction of the same, substantially as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to. make and use the same, I will now proceed to describe itsconstruction, referring to the accompanying drawings.

Figure 1 is a perspective view of part of a gage. Fig. 2 is a horizontalsection of the same. Figs. 3, 4, 5, and 6 are detail views, showing thegage in different stages of construction.

A represents a milk-can of the usual form provided with a cream-gage, B.This gage is stamped from asingle piece of metal, with the opening a andflange b at the sides and ends. These flanges are bent or stamped inwardthe thickness of the glass panel 0, and then at right angles to form thewings 6. These wings b are then bent at a point, which will of which thefollowing is a specifistill leave narrow but now double wings orprojecting flanges backward over themselves, and extending to theopening a, in order to hold the glass panel in place when inserted, asseen at 0. In making the gage, having struck out the blank and made theopening a, the gage marks and the flanges b and the wings b are stampedout at one operation, leaving a depression for, and the thickness of,the glass panel to be inserted. Having the wings I) bent as beforeshown, the glass is inserted, and by pressing tightly together thedouble portions of the flanges or wings I) the extended part is bentdown upon the glass panel, pressing it against the flanges b on thereverse side and holding so firmly and tightly as to prevent the escapeof liquid. The gage is then passed through an opening in the side of thecan from the inside, with the double flange or wings I) resting againstthe body of the can, forming a tight joint inside, and leaving nothingfor the milk to cling to. The inside surface is smooth and does notinterfere with the perfect cleaning of the can. The gage is secured inplace by having its glass panel or raised portion passed through theopening made in the side of the can and its flanges resting against theinside of the main body of the can, as represented in Fig. 2. It is thensoldered to the can, the melted solder spreading out under the flanges,and a tight joint formed, while at the same time no uneven projectionsare formed which are difficult to clean, and thus injure the fresh milkwhen poured into the can. It will be understood that the flange extendsentirely around the gage or panel, at the ends as well as the sides,made entirely as just described.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a cream-gage, the combination of the can formed with an opening initsside, of the blank or frame B, stamped from a single piece of metal,with the usual gagemarks, the flange 6, opening a, and wings I), andglass panel 0, the said wings being bent over backward upon themselvesat a point so as to leave a narrow projecting double flange or wings b,extending and overlapping the glass panel a, substantially as and forthe purpose set forth.

2. In a cream-gage, the combination, with a transparent frame, of asheet-metal frame formed with the opening a and flanges b, said flangesbeing bent outward and then back upon themselves,and overlapping thepanel, thus forming wings 1), adapted to be secured to the sides of thecan, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

CLARENCE L. COLBY.
